The phone that everyone is talking about might have been leaked in a video posted by 52Samsung. In the video, we can see that the phone looks very simular to the S3. The only major hardware difference is that the side looked like metal (most likely plastic still though). There also looks to be an updated version of TouchWiz installed.
The Samsung Galaxy S4 will be officially announced tomorrow (March 14th) so we can see if this video is really showing off the real S4.
Let us know if you think this is the real S4 and if you would buy this.
